Flexible stretchable layered composite structure containing liquid metal

A flexible stretchable layered composite structure containing liquid metal sequentially comprises a first elastic layer, a liquid metal layer and a second elastic layer. A plurality of supporting bodies are adhered to the surface, facing the second elastic layer, of the first elastic layer, and/or a plurality of supporting bodies are adhered to the surface, facing the first elastic layer, of the second elastic layer; the liquid metal layer fills the remaining space between the first elastic layer and the second elastic layer. Through the layered composite structure formed by the elastic layers and the liquid metal interlayer and the arrangement of the supporting body, the flexible and stretchable packaging piece with excellent sealing performance can be provided, and the problem that the two elastic layers are in contact due to stretching or bending and the like in the use process, so that the barrier performance is reduced, and packaging failure is caused is effectively solved. Based on the composite structu
